Earlier quoted context omitted.
Most docs are overworked for many, mostly bad reasons. Clinical overload is one thing, but healthcare is more like drowning in admin work, these days. So mostly yes, but the true answer is more complex than I can write about in a comment.
The US has 26.1 doctors per capita, while Germany has 42.5, which is a middle-of-the-road number for the developed West. Do you accept the criticism that the US simply artificially limits the supply of doctors, which leads to overwork for physicians, and worse health outcomes for patients? Do you think most doctors would take less hours for a somewhat lower salary if you it was possible?
Young docs would absolutely work less for less if possible, I think. Old docs wouldn't. IMO, that's reflected in the rise of big network providers such as Kaiser and friends.
In Europe, access to care is better IMO mainly because both patients and docs are far less aggressive, and often quite happy just doing nothing. Which is in fact the true problem about US healthcare: the culture of absolutism.
